Does Tonsillectomy Help In The Treatment Of Throat Ulcers And Canker Sores?

I have been getting ulcers in the back of my throat as well as a bunch of canker sores at the same time. We thought it was iron deficiency, and I’m taking iron so that wasn’t it. We thought it was because of my diet and my family doctor said try making smoothies every day and adding you hurt so we did I had one almost every day or every other day for a year still got them. So my mom thought it was because Of coffee so I stopped having coffee still got them. I saw a ears nose and throat docter he said there isnt to much we can do its normal to get cankor sores he gave me a presciption i could use when it got bad and it didnt work the only thing that worked was the antibiotivs but i will sooner or later become immune to them if i use it as often as i get these? I take 1 10mg of fluoxetine and 1. 15 mg fluoxetine as well as 10 mh of dexadrine and 15 mg of dexadrine to and iron. I am 17 years old i have tryed everything i cna think of idk what to do it wasnt as consist but now it is when i get it it can easily last for a month or longer and i tryef gargeling and everyday when i had cankor sores it didnt really help. I get the same ulcer on either the left or right side of my tonsils So my best friends mom Said something about a tonsillectomy would that help my situation at all
